FCD (Flow Conditioning Device)
It’s Not Your Meter. It’s Your Pipes. The FCD Corrects the Flow
During high-demand periods, gas and vapor that form inside the meter because of your building’s piping cause commercial water meters to over-read. The FCD (Flow Conditioning Device) installs immediately after your meter in about an hour and creates accurate measurement conditions — Under 0.8 psi pressure loss, no usage reduction, and savings starting with your first full billing cycle.

Direct answer: The Flow Conditioning Device (FCD) is a custom-built product that installs immediately downstream of a facility's water meter and corrects meter over-registration caused by gas and vapor that form inside the meter during high-demand periods in the building's piping. It requires no power, causes Under 0.8 psi pressure loss, and is installed by a licensed plumber or mechanical contractor with water off for approximately one hour. Built from 316L stainless steel (titanium available by special order) and certified to IAPMO, NSF/ANSI/CAN 61, KIWA, GMP, and SQF standards, the FCD delivers a water and sewer bill reduction of typically up to 30% (46% highest documented), with about 90% of customers reaching full ROI in under 12 months. It's backed by a 6-month money-back guarantee (installation labor non-refundable) and a lifetime warranty transferable to a new building owner.

Why Your Water Meter Reads More Than You Actually Use — and Why It Happens in Every Facility
Commercial water meters don’t just measure water — they measure everything that passes through them. During high-demand periods, high velocity drops the pressure inside the meter so sharply that the water breaks apart into gas and vapor, and these pass through your meter alongside actual water. The meter counts them as billed volume. You pay for them on your water bill — and pay again on your sewer bill, since sewer charges are commonly calculated from metered water consumption.
This can happen in any commercial or industrial facility — in food processing plants and semiconductor fabs, in hospitals and university dormitories, in hotels and apartment buildings, in car washes and golf courses, in stadiums and data centers. The specific operations that generate the over-reading vary by industry. The mechanism and the solution are the same everywhere: gas, bubbles, and turbulence created at high demand inflate the meter reading.
What’s Inside the FCD — Four Components, One Installation
The FCD installs immediately after your water meter on the consumer side of the connection. It addresses the four root causes of
meter over-reading simultaneously — all in a single device, in a single installation, in a matter of an hour.
For the physics behind it, see How the FCD Works.
Air & Gas Separation
The FCD creates a slight static back-pressure that forms a laminar-like flow profile extending back through the meter. That steadier pressure means far less gas and vapor form, so the meter records water rather than a mix of water, gas, and vapor.
Pressure Regulation
Regulates flow and pressure through the meter. Reduces water hammer and pressure surges from on-off cycling and variable demand.
COMPONENT 3
Check Valve*
Decreases water hammer events. Minimizes pressure surges and prevents reverse flow through the meter. Reverse flow and pressure spikes are two of the primary mechanisms that create gas and turbulence in the water lines.
* Note: Some FCDs do not have check valves.
COMPONENT 4
Turbulence Reduction
Stabilizes flow through the meter and inhibits vortex flow, reducing the turbulent, spinning flow pattern that causes meters to over-count. Particularly effective during CIP cycles, tank filling, and sprinkler or irrigation system operation. Basically, in “open-valve” operations.
Under 0.8 psi pressure loss — This Is a Fundamental Design Characteristic, Not a Feature Claim
Under 0.8 psi pressure loss means nothing downstream of the FCD changes. Not in your building, not in your process, not in your production line, not for your guests or tenants or patients or students. The FCD conditions the flow through the measurement zone — it does not restrict it. Pressure loss across the FCD is under 0.8 psi across all flow conditions, so system pressure at every downstream connection is effectively the same before and after installation.
This is the most important single characteristic of the FCD for operations that cannot tolerate pressure variation — hospitals, semiconductor fabs, food processing plants, data center cooling systems, athletic facilities, and any operation with pressure-sensitive equipment or service standards. Under 0.8 psi pressure loss is not a target or a design goal. It is how the FCD works by design.

Water bills, pipe and meter sizes are required to perform an accurate cost savings analysis.
Will the FCD affect water pressure anywhere in my facility?
No. Under 0.8 psi pressure loss is a fundamental design characteristic of the FCD — not a feature claim or a performance target. The device conditions the flow through the measurement zone without restricting it; pressure loss across the FCD is under 0.8 psi across all flow conditions. System pressure at every downstream connection in your facility is effectively unchanged after installation.
Do I need to reduce water usage to see savings?
No. The FCD corrects what your meter was registering, not how much water your facility actually uses. Your operations, your processes, your services, and your water delivery all continue exactly as they do today. The savings come entirely from correcting the meter inaccuracy — not from conservation or usage reduction of any kind. There is NO reduction in water consumption, only in water cost.
How long does installation take and does it disrupt operations?
Installation takes normally about an hour and requires only a brief water shutoff — typically under one hour for straightforward configurations. The FCD installs on the main water line immediately after the water meter on the consumer side of the connection. No access to internal facility systems, process equipment, or operational areas is required beyond the meter location itself.
When do savings appear?
Savings appear on your next water billing cycle (and on the next sewer billing cycle if connected to your water usage) after installation. There is no ramp-up period and no waiting period. The meter reads accurately from the moment the FCD is installed — and the next bill(s) reflects that accurate reading.
What pipe sizes and meter types does the FCD work with?
The FCD works with any pipe size and any meter type. It is sized to your specific pipe configuration at the time of order. The standard material is 316L Stainless Steel. Titanium and specialty alloys are available on special order for applications with specific material requirements.
What if we don't see the expected savings?
Water Flow Innovations offers a 6-month money-back guarantee — no questions asked. If you are not satisfied with the savings within 6 months of installation, you will receive a full refund for the FCD. Installation cost is non-refundable. The FCD also carries a lifetime transferable warranty that stays with the device and the property through any ownership or management change.
Can the documented savings be used for LEED, ESG, or sustainability reporting?
FCD savings appear on utility bills as measurable reductions in metered water and sewer charges, which supports cost-savings documentation. Because the FCD corrects the meter reading rather than reducing actual water use, confirm with your sustainability consultant before reporting results as water conservation.
